Wedding Thank You Card Calculator
Work out how many thank you cards to order, what they'll cost to post, and a realistic writing schedule. One card per household — not per guest.
How to Use This Calculator
- Enter your total guest count — the number of people who attended your wedding. The calculator uses this to suggest how many household cards you'll need (roughly 60% of your guest count, since couples and families share one card).
- Confirm your household count — click "Estimate for me" for a quick figure, or enter your exact household count if you've counted from your guest list. This is the most important number: it determines how many envelopes you'll need to address.
- Add extra recipients — include anyone who sent a gift but couldn't attend, vendors you want to thank (photographer, caterer, florist), and wedding party members who deserve a personal card.
- Review your total and schedule — the calculator adds a 10% buffer for mistakes and shows a writing plan at three different daily paces. Toggle the cost estimate to see your total spend on cards and stamps.
How Many Thank You Cards Do You Actually Need?
The most common mistake couples make is ordering one card per guest. You don't need that many. Thank you cards go to households — a couple counts as one card, a family of four counts as one card, and a single guest counts as one card. For most UK weddings, households run at roughly 60% of the guest count.
| Guest count | Estimated households | Cards to order (with 10% buffer) |
|---|---|---|
| 50 guests | ~30 households | ~33 cards |
| 80 guests | ~48 households | ~53 cards |
| 100 guests | ~60 households | ~66 cards |
| 120 guests | ~72 households | ~80 cards |
| 150 guests | ~90 households | ~99 cards |
| 200 guests | ~120 households | ~132 cards |
These figures assume 0.6 households per guest — a reasonable UK average for wedding guest lists, which tend to include a mix of couples, families, and single friends. Your actual ratio depends on your guest list: a guest list of mostly couples and families will be closer to 0.5 households per guest; a younger list with lots of single friends will be closer to 0.7.
Beyond household cards
Don't forget to add cards for:
- Non-attending gift senders — friends or relatives who sent a gift but couldn't come to the wedding. They absolutely deserve a card, and they're easy to overlook when you're only thinking about guests.
- Vendors — your photographer, florist, caterer, cake maker, or venue coordinator. A handwritten note goes a long way in the wedding industry, and it's a thoughtful accompaniment to any online review.
- Wedding party — bridesmaids, groomsmen, ushers, flower girls' parents, and anyone else who played a special role. These are separate from any wedding party gifts — a card adds a personal touch.
When to Send Thank You Cards After a UK Wedding
UK wedding etiquette asks that all thank you cards are sent within three months of the wedding. In practice, most guests notice if cards take longer than that, and some couples leave it so long that the task becomes increasingly daunting until it doesn't happen at all. The best approach:
- Start within two weeks of returning from your honeymoon. Your memories of the day are still fresh, which makes personalising each card much easier. Waiting months means you'll struggle to remember who gave what.
- Set a daily target and stick to it. Even three cards per day gets you through a list of 75 households in 25 days. Five cards per day and you're done in two weeks. The calculator above shows your schedule at each pace.
- Write cards for pre-wedding gifts immediately. If someone sent a gift before the wedding (perhaps posted from overseas), aim to post their card within two weeks of the wedding day — don't wait until all the other cards are written.
- Post all cards by three months. This is the widely accepted UK deadline. Beyond this point a brief explanation ("We've been getting settled in our new home…") softens the lateness.
What to Write in a Wedding Thank You Card
A good wedding thank you card takes about two minutes to write and follows a simple structure:
- Use their name. "Dear Auntie Sarah and Uncle James" beats "Dear guests" every time. Using names signals that you're writing a personal note, not a form letter.
- Thank them for the specific gift. "Thank you so much for the beautiful Le Creuset casserole dish" is far more meaningful than "thank you for your generous gift." If they gave money, mention the amount or what you plan to use it for ("towards our new kitchen").
- Add one personal line. Mention a specific moment from the day ("We loved having you on the dance floor at midnight!") or reference something about them ("We can't wait to try it out when you next come to dinner").
- Close warmly. "With love, [Both names]" or "Warmly, [Names]" is enough. Both partners should sign every card.
Aim for three to five sentences. Longer is not better — a tight, personal note is more meaningful than two paragraphs of filler. Split the writing between you to avoid handwriting fatigue: one partner writes the main note, the other adds a line and signs both names.
For monetary gifts
It can feel awkward to mention the amount, but doing so confirms the gift arrived safely — especially for cash in envelopes. Try: "Thank you so much for the generous cheque — we're putting it towards our honeymoon / new sofa / kitchen renovation." You don't need to be exact: "towards our honeymoon fund" works well even if you haven't decided exactly how to spend it yet.
What Do Wedding Thank You Cards Cost?
The total cost splits across cards and postage. Both vary considerably depending on your choices:
Card costs
Card prices range enormously. A rough guide for common UK options:
| Card type | Typical price per card | Notes |
|---|---|---|
| Basic printed cards (packs) | 30p–60p | Generic designs; often sold in packs of 10–25 from supermarkets or stationery shops |
| Personalised printed cards | £1.00–£1.50 | Online print services (Moonpig, Photobox, Papier) — custom design, your photo |
| Premium photo cards (stationer) | £2.00–£3.50 | High-quality stock, foil finishes, bespoke design from a wedding stationer |
| Handmade cards | 50p–£1.50 (materials) | Time-intensive but personal; factor in your time if making yourself |
Postage costs (Royal Mail, 2026)
Most standard thank you cards fall within the Royal Mail letter format (up to 240×165mm, under 100g). Oversized or thicker cards may fall into the large letter category.
| Service | Price per stamp | Typical delivery |
|---|---|---|
| Second class (letter) | 91p | 2–3 working days |
| First class (letter) | £1.80 | 1–2 working days |
| Second class (large letter) | £1.55 | 2–3 working days |
Second class is perfectly acceptable for thank you cards — there's no urgency once you're within the three-month window. Buying stamps in books of 12 or books of 25 from the Post Office or Royal Mail online saves queuing.
Frequently Asked Questions
How many thank you cards do I need for my wedding?
You need one card per household, not one per guest. A couple attending counts as one card; a family of four counts as one card. Start with your household count, then add any non-attending gift senders, vendors you want to thank, and wedding party members. Add a 10% buffer for mistakes and last-minute additions — that's your total to order.
When should I send wedding thank you cards?
UK etiquette is to send all thank you cards within three months of the wedding. Aim to start writing within two weeks of returning from your honeymoon while memories are fresh. Cards for gifts received before the wedding should ideally go out within two weeks of the wedding day.
Do we need to send thank you cards to everyone at the wedding?
You should send a card to every household that gave a gift — whether they attended or not. For guests who attended but gave no gift, a card is a kind gesture but not strictly required. Always send cards to your vendors if you want to maintain a good relationship and leave a positive review.
How long should a wedding thank you card be?
Three to five sentences is the right length. Thank the person by name, mention the specific gift or contribution ("the beautiful vase" or "your generous cheque"), say how you will use or enjoy it, and close warmly. Generic cards feel impersonal — even one specific detail makes a significant difference.
How much does Royal Mail postage cost for a thank you card in 2026?
A standard UK second-class stamp costs 91p (April 2026). First-class costs £1.80. Cards that are larger or thicker than the standard letter size (up to 353×250×25mm, under 100g) fall into the large letter category at £1.55 second class. Use the cost estimate section above to get a total postage figure for your order.
Should we both sign the thank you cards?
Yes — both partners should sign every card. A practical approach is to split the writing: one partner handwrites the body of the card, the other adds a personal closing line and signs both names. Alternatively, divide by surname initial — A–M to one partner, N–Z to the other.
